MA-18422 Locate the misc partition by name

Locating the misc partition by ID can help reduce the boot
time but error may happen if the ID of the misc partition
is changed. Moving the misc partition to the start of the
GPT and locate the partition by name is another option but
it will break the backward compatibility as the GPT is
changed.

part_get_info_by_name() will loop the PTE and return the
matched partition info, but it will cost much time as it
will reload the whole PTE from storage in each loop.

This commit provides part_get_info_efi_by_name() to support
return the partition info by name without reloading the whole
PTE.

Test: A/B slot switch in dual bootloader.
